WebMar 11, 2024 · Secret-key encryption algorithms use a single secret key to encrypt and decrypt data. You must secure the key from access by unauthorized agents, because any party that has the key can use it to decrypt your data or encrypt their own data, claiming it originated from you. WebThis class represents a factory for secret keys. Key factories are used to convert keys (opaque cryptographic keys of type Key) into key specifications (transparent representations of the underlying key material), and vice versa. Secret key factories operate only on secret (symmetric) keys.
